The experienced defender has been given a one-year ban after abandoning Portugal's training camp last month shortly before a Euro 2012 qualifier
This means that Carvalho will sit out the Euro 2012 finals if Portugal qualifies for the showpiece event in Poland and Ukraine.
The 33-year-old walked out of the national side's training camp last month without explanation after learning he would not start in a Euro2012 qualifier against Cyprus.
Later that day, Carvalho issued a statement to announce his retirement from football, saying he had been 'disrespected and hurt in his dignity'.
According to the FPF regulations, the maximum penalty a player can face for a situation such as this is a two-year suspension.
If the federation decided to report the case to Uefa, Carvalho could then find himself in a even worse situation, as he could have to serve a Champions League ban of up to three months.
However, Portugal coach Paulo Bento has ruled out that scenario, insisting he is looking to put the incident behind him.
